Definitions

  • the present invention relates to an apparatus for treating hair fibers.
  • the international request WO 2014/064660 describes a device for applying a cosmetic product to the hair, exposing it to steam, subjecting it to heat treatment and combing it.
  • a hairdressing appliance comprising a portable treatment unit having two arms configured to form a clip provided with two heating contact surfaces, defined by plates arranged opposite each other, which simultaneously allow the clipping of a strand of hair.
  • This processing unit comprises vapor diffusion means configured to diffuse vapor from a first of the two surfaces towards the second.
  • One of the arms comprises a comb arranged downstream or upstream of one of the contact surfaces.
  • the devices of the prior art do not give complete satisfaction, in particular from the point of view of the results obtained on the hair fibers, for example in terms of volume and discipline.
  • the use of these devices has also shown that the steam outlet orifices could become clogged, in particular because of the various elements which may be present on the user's hair, thus reducing the performance of these devices.
  • the confinement structure allows at least partial confinement of the vapor outside the contact surfaces, that is to say outside the contact surfaces.
  • hair encompasses the corresponding human or animal keratin fibres, as well as synthetic fibers called "extensions" which are sometimes applied to the natural hair of a person by various means, in particular by gluing, in order for example to modify the look of a person's natural hair.
  • contact surface is meant a hair treatment surface, preferably a smoothing surface, for example constituted by a smoothing plate which is advantageously heated as will be detailed below.
  • Each treatment surface is intended to be in contact with at least one lock of hair during the treatment of the hair.
  • connection structure is meant, as indicated above, at least one part or set of parts which allows at least partial confinement of the steam generated by said at least one steam outlet.
  • the term "recess” advantageously denotes a hollow zone which extends opposite the steam outlet and which is intended to accumulate, contain or even at least partially confine the steam. It can extend longitudinally.
  • the recess has a concave shape defining a volume inside which steam can accumulate. It can advantageously form a groove.
  • the axis of the throat belonging to the median plane of the throat can be parallel or even merge with an axis of the steam outlet or make a non-zero angle, for example equal to 45° or less, with the axis of the steam outlet.
  • the recess may be delimited by the same part or by several parts, in particular be a U-shaped hollow in cross section.
  • the at least partial confinement obtained according to the invention makes it possible to locally accumulate steam, advantageously outside the contact surfaces, in the volume located between said at least one steam outlet and the confinement structure, this which can lead to a reduction in the flow of steam needed to treat the hair. It is possible, because of the reduction in the quantity of steam necessary for the treatment, to prolong the autonomy of the apparatus and to reduce the quantity of residual humidity of the hair on leaving the apparatus.
  • the containment structure can contribute to a better distribution of the steam longitudinally, between the steam outlets. The lock of hair can thus be treated more homogeneous in the transverse direction.
  • the partitioning created by the containment structure makes it possible to apply most of the steam only locally, during the passage of the lock of hair in the zone located between said at least one steam outlet and the throat, zone can thus be qualified as a steam application zone.
  • said at least one steam outlet is located at a distance, that is to say separated, from the adjacent contact surface and not within the latter as in the prior art, leads to not applying of steam on the hair area between the contact surfaces.
  • the heat treatment generated by the contact surfaces is thus dissociated from the application of steam originating from said at least one steam outlet.
  • the apparatus according to the invention can be autonomous, with an integrated water reservoir, or comprise a handpiece which is formed by the arms and a base station to which the handpiece is connected, which comprises a reservoir containing the water for steam production.
  • the apparatus preferably comprises a comb having teeth, carried by one of said arms.
  • said at least one steam outlet can be inserted between the comb and the contact surfaces.
  • the comb can thus participate in the confinement of the vapor.
  • the confinement structure advantageously comprises a cowling for the comb.
  • a cowling can cover only one side of the teeth of the comb.
  • the cowling covers both sides of the teeth of the comb in the direction of passage of the hair.
  • the cowling only covers the tops of the teeth.
  • An advantage of cowling is that it can help contain vapor. Another of its advantages is that it forces the strand of hair to penetrate, during its passage, between the teeth of the comb, which improves the efficiency of combing the hair.
  • the apparatus is perfectly ambidextrous.
  • the aforementioned groove and the cowling of the comb can be separated, on the confinement structure, by a rib arranged parallel to the groove.
  • This rib can be formed by a portion of a part which also defines the cowling and the throat, this part being made in one piece by material molding for example.
  • Such a rib makes it possible in particular to limit the risk of contact between the back of the throat and the lock of hair
  • the confinement structure is for example located close to the contact surface, preferably the plate, carried by the same arm.
  • the confinement structure can be fixed on the plate, that is to say on the contact surface, or on the contrary be independent of the plate, for example with a slight functional play, which allows the plate to keep certain degrees mobility, for example being able to pivot on itself.
  • one of the arms carries one of the contact surfaces, said at least one steam outlet and optionally the comb, while the other of said arms carries the other of the contact surfaces, the confinement structure and possibly the cowling of the reed.
  • the steam outlet or outlets are set back with respect to a plane defined by the edge of the contact zone between the contact surfaces (in the absence of hair) on the side of the steam outlet or outlets and the base of the comb teeth.
  • This makes it possible to prevent the hair from coming into contact with the steam nozzles and therefore to limit the risk of clogging or obstruction of the latter.
  • the plane of closure of the contact surfaces is located above the bottom of the comb in the closed position of the device, which makes it possible to avoid the detachment of the hair from the head at the start of hair treatment, known as the "cushion effect". ".
  • the hair can be correctly placed in rectilinear tension between the comb and the contact surfaces.
  • the confinement structure is preferably located at least partially, or even totally, set back relative to a plane connecting the edge of the contact zone between the contact surfaces on the side of the confinement structure and the top of the comb when the arms are in a close configuration, which makes it possible to limit the risk of contact between the confinement structure and the lock of hair.
  • the containment structure may comprise a single piece or several pieces assembled together and produced for example by molding in thermoplastic material, for example PBT, or in thermoplastic elastomer material such as for example TPE.
  • the groove may have a width, measured perpendicular to the longitudinal axis of the contact surfaces, preferably of the plates, and parallel to the heating surfaces in close configuration of the arms, of between 1 and 20 mm, preferably between 2 and 12 mm and advantageously substantially equal to 4 mm.
  • the groove may have a depth of between 1 mm and 15 mm, preferably between 2 and 5 mm, and advantageously substantially equal to 2.5 mm.
  • the throat does not include any heating means of its own, such as an electrical resistance. The temperature of the surface in the bottom of the throat preferably comes almost exclusively from the heating of this surface caused by the projection of steam.
  • the edges of the groove preferably do not come into contact with a surface of the opposite arm carrying said at least one steam outlet.
  • the cumulative steam flow for the or all the steam outlets is preferably between 0.5 and 1.1 g/min, being preferably less than or equal to 3.5 g/min, better still less than or equal to 1 g / min, for example between 0.7 g / min and 0.9 g / min.
  • the steam outlet or outlets are preferably supplied with steam by a vaporization chamber itself supplied with water by a pump.
  • Said at least one steam outlet advantageously comprises at least one steam ejection channel and at least one steam ejection nozzle.
  • This channel can be oriented perpendicular to the longitudinal axis of the corresponding arm.
  • the nozzle can have the same orientation; thus, the steam is emitted in a direction perpendicular to the contact surfaces, and preferentially to the plates, that is to say in a direction perpendicular to the direction in which the lock of hair travels in the device.
  • the nozzle or nozzles are of conical shape with a circular section, and the section of the nozzles widens in the direction of the outlet of the nozzles.
  • Said at least one steam outlet may comprise between 3 and 10 steam ejection nozzles, preferably 7 nozzles.
  • the maximum width of a nozzle is for example between 2 mm and 8 mm and advantageously substantially equal to 5.3 mm.
  • the height of a nozzle is for example between 2 and 10 mm, preferably between 3 and 6 mm, advantageously substantially equal to 3.5 mm.
  • the distance between two adjacent nozzles, measured between the axes of the latter, can be between 5 and 20 mm and advantageously substantially equal to 11 mm.
  • the throat is at a distance from the upper end of the steam ejection nozzle or nozzles, this distance being for example between 3 and 20 mm, preferably between 5 and 10 mm, when measured along the longitudinal axis of the arm in closed position.
  • the steam is preferably steam, in particular without additive.
  • the or each steam ejection nozzle is preferably mounted at one end of the or each steam ejection channel.

  • the steam outlets 20 are 7 in number, but the invention is not limited to a particular number of outlets.
  • the latter are located at a distance from the plate 10 and not within it. This makes it possible not to apply steam to the portion of the hair positioned between the plates 10 and 11 at a given moment, and also to preserve the steam outlets from any risk of clogging or clogging by elements which could be on hair, such as leftover cosmetics or dandruff.

  • the volume V in which the vapor is mainly confined is delimited on the interior side by the lateral edges 37 and 38 of the plates 10 and 11, on the outside by the teeth 31 of the comb, and above by the groove 25, the rib 41 and the cowling 40.
  • the sealing element 150 also participates in delimiting this volume and to confine the steam.
  • This volume V can be between 2000 and 10000 mm 3 being for example close to 5500 mm 3 .
  • a volume V of vapor is therefore confined between the comb 30, the confinement structure 21, the plates 10, 11, and the vapor outlets 20.
  • At least one vapor barrier 43 can be placed on the arm 4 at the end of the row of vapor outlets 20, on the proximal part 4a side, so as to confine the vapor on that side.
  • the plates 10 and 11 are not centered on the device 1 but offset towards a side edge 6 of the device 1, while the comb 30 adjoins parallel thereto the other side edge 7 of the device 1.
  • the row of steam outlets 20 extends between the comb and the plates 10 and 11, parallel to these and to the longitudinal axis Y.
  • the treated lock of hair follows, relative to the device 1, the direction illustrated in the figure 4A , taking into account the movement of the device along the wick.
  • a given area of the hair contacts the teeth 31.
  • the hair is forced by it to pass between the teeth 31 of the comb 30.
  • the aforementioned area of the lock then comes in the volume V where the steam can accumulate, and it is exposed there to the steam emitted by the steam outlets 20.
  • the area in question is pinched between the heating surfaces 12 and 13, where it undergoes a heat treatment without steam.
  • the appliance may comprise a hair product applicator, arranged for example at the edge of the contact zone between the plates or before the comb, or inserted between the comb and the vapor confinement zone, or between the latter and the plates.
  • the containment structure can be modified.
  • the groove 25 can be given a different shape or orientation.
  • the rib that separates the groove from the cowling in the example of the figure 8 is deleted.
  • the groove 25 has, in this example, a transverse axis G passing through the bottom of the groove, said axis G forming a non-zero angle ⁇ , equal in this example to 45° with the axis X of the steam outlet.
  • Axis G is oriented such that groove 25 is generally turned towards the comb, as shown in the figure.
  • a helical spring 162 which bears at one end in the bottom of the housing defined by the cylindrical wall 161 and at the other end against the head 160.
  • the containment structure 21 is set back by relative to the plane W connecting the edge of the contact zone between the plates 10 and 11 in the close configuration of the arms 4 and 5, and the top of the comb 31 to avoid the contact of the lock of hair with the confinement structure 21 while providing a certain volume of vapor between said structure 21 and said wick.
